Biomass-fueled domestic heating equipment is increasingly being used, due to the low price of biofuels and the ease of finding them in distribution and sale networks. However, it is not possible to use just any type of biomass in these equipment, since its quality must be very high so that its performance is not too low. Also, the pelletization of the waste to be used is necessary, since a constant granulometry is necessary for the automatic feeding of the equipment. Among the waste generated by the industries of granulated cork are grinding powder and granulometric separation powder. Of these two, only granulometric separation powder could be used as raw material for pellet manufacture for use in small domestic biomass equipment, due to its low ash percentage. In this work, the combustion in a small domestic pellet stove is studied for different combinations of pellets made from granulometric separation powder and its behavior in this type of equipment. For that purpose, five different types of pellets made from different granulometry combinations were used. A commercial Edilkamin Junior pellet stove with a power of 5.8 kW. Combustion gases, such as O2, CO2, CO, H2, NOx and SO2, as well as combustion efficiency and chamber temperature were analyzed.
